VDO 0-10 bar 2 wire sensor calibration

[Wolf_Tm]

Hi,
really not able to get that VDO 0-10 bar 2 wire sensor working with VEMS ecu.
Tried the Wizard but readings are always at zero.

In Motec ecus I do use the same sensor with great results using both their internal or external pullups, and here is their cal table for it:

it should work, just it's not linear i believe so you wont get acurate results on that use proper 3 wire sensor instead
even motec seems to use some kind of adapter for them

Their adapter is just a pull-up if you want to wire the sensor to an aux volt input pin, no need of the adapter of you connect it to an aux temp pin that already has internal pull-up.
I didn't use any pull-up with vems as I read it already has one internally... Correct?
So why wizard won't work?

depending on channel you use ones who are @5v unconected has 2.7k pullup, it's the sensor is dead or you are doing it wrong does voltage changes on that analog input when pressure changes?

Only channel 6 and 7 have internal pull up.

Channel 0, 1, 2 and 5 are 0-5v input (no pull up)

Channel 3 and 4 reserved for EGT1 and EGT2

Not all are connected to EC18 and will depend on your box. Check your cheat sheet that came with your box.

I would agree with Kamuto, use a three wire transducer (+5v, Ground and signal).These type of transducers have a signal conditioning circuit built into them, this will give a 0.5-4.5v linear output. No pull up required as the transducer outputs a voltage signal, rather than a ground signal.

The sensor is on Channel 7, and the raw is 0.14 at hot idle and 0.24 at 2000 rpms, for example...

Hi Kamuto,
which 3 wire pressure sensor would you suggest with VEMS?
Thanks

any linear one,  but I usually use that one, 06E906051K most reliable, 0.5-4.5v 0-10 bar

Hi Kamuto,
do you have the pinout of this transducer?
I can't sort it out, and I am almost afraid I got a faulty sensor!
